Specification of Letters Patent.

- Patented Sept. 11, 1906.

Application filed February 29.1904. Serial No. 195,812.

' To all whom it may concern:

Be it known that we, JOHN EBERHARDT and HERMAN WEGHORST, citizens of theUnited States, residing at Chicago, Illinois, have invented new anduseful Improvements in Steam Turbine-Engines, of which the following isa specification, reference being bad to the accompanying drawings,forming a part hereof, and in which- Figure 1 shows our new steam-enginein elevation. Fig. 2 shows a central longitudinal section through theengine. Fig. 3 shows in perspective afragment of a circle ofbucketcapping with buckets thereto, the buckets being out free from theelements A or B. Fig.

4 shows the inner or rotating end of our engine with fragments of thecover broken away and the caps of the buckets removed at one of saidplaces and the other or lower places without buckets, showin thesteamchamber and passages to it. ig. 5 shows the fixed or static part Bof our engine open as seen from the entrance end. Fig. 6 shows theactive part A, which fits into and works in said static part.

Like reference letters denote like parts throughout.

The object of our invention is to produce a turbine-engine in which thewheel A, or active element, discharges moving jets of steam at itsperiphery toward the axis of the engine upon fixed buckets, so as tocause said jet or jets to move away from the fixed buckets e, whichconstitute the first or outer circle of buckets of the part or elementB, and, further, to deflect the steam from said fixed bucket upon amoving circle of buckets forming a part of the disk A, which containssaid jets, which in turn deflects the steam-jet upon a circle of fixedbuckets, from which the steam is again deflected on a circle of bucketsforming a part of the moving element of our device, as before, and so onindefinitely as long as the steam so worked can produce added force toour said active element or sets of circles of rotating buckets. Toattain said desirable ends, we construct our said new turbinesteam-engine in substantially the following manner, namely: We make acircular box of two separable parts a, and (1, the latter being but acover bolted to the former. A steam-pipe centers at the center of saidbox from one side and continues out of the other side of said box as asolid shaft 0/, and from the end of the said tubular shaft or steampipeare openings forming parts of openings 1) in opposite arms, whichterminate in a steamchamber 0 at the ends of said arms, from which thereis an opening (1 at an angle directed toward the center of fixed andconcaved buckets, as at 0, Fig. 3, in which the arrow indicatesthedirection of said opening and jet from it. The inner side of saidsteamchamber forms a part of a vertical flange e, continued on around atthe outer edge of a rotatable disk A, which forms the active element ofour engine. Said flange extends to the opposite fixed or static elementB of our .en ine as closely as permissible to allow it to sti 1 moveover it freely, and it also moves as closely to the edges of the circleof fixed buckets e, which form an integral part of said static elementB. Said flange confines the steam from the annular channel 'i, requiredfor the steam-chests c. The buckets c are an integral part of the staticpart B, and they are united or cast to a ring e, of which the generalconstruction for rings e f 2 g 72. is shown more clearly at c", Fig. 3,and within said ring of fixed buckets is another ring of buckets f,which form an integral part ofthe active or rotating element A, whichare under an annular cap f and within said ring of buckets is anotherring of buckets 9 under the annular cover 9 forming an integral part ofthe part B, and within said ring is another ring of buckets 72. underthe annular cover 7L2, which form an integral part of the rotatingelement A. Said rings of buckets pass between each other telescopicallyand fit as nearly steam-tight within their places as possible to workthe parts freely.

In 0 eration the steam issues from the inclined oles (ports) (1 andimpinges on the stationary buckets c, and thereby the steamchest isforced to move and so engage the said steam-jet with another bucket ine, and so on.

-At the same time the said jet is deflected from said fixed buckets 0against the next ring of buckets f, which move integrally with c, andthen the said jet is again reflected from saidmoving buckets upon thefixed buckets g, and from them said jet is again reflected against themoving buckets h of the last and inner ring of buckets, after which itsforce is so far spent as to be of little or no farther value as adriving force.

The buckets are concave and are itched at such distances and angles aswill )est facilitate the action of the steam-jet from one circle ofbuckets onto the other. substant'glly as shown in Fig. 4.

The rings a g k capping the buckets I said branches, jet-orifices insaid chests and strengthen them and, with the other parts around them,inclose the steam, so as to force it to act from bucket to bucket.

A short wall t within the ring of buckets it closes the jet at its endSaid jet is shown at the port d as j, which ends at y'*. Said wall Ifprevents the too early exhaustion from the inner ring of buckets.

What we claim is- 1. The combination with telesco ed rings of bucketsalternately stationary andh'otatin and an axial steamentrance with radiabranches, of steam-chests moving exterior to a fixed ring of buckets andsteam-orifices from said chests for jets on said fixed buckets, bucketsactuated by jets deflected from said fixed buckets and exhausted towardthe axis.

2. The combination with telescoped rings of buckets whereof,alternately, one set is fixed and the other rotates, radially, withinit, and a steam-chest exterior to said outer ring, of a tubular axle andtubular arms therefrom to said steam-chests and steamorifices from saidchests directed for jets from said chests impinging, alternately, onfixed and moving buckets.

3. The combination with a fixed and a rotary element on a combinedsteam-pipe and axle, of rings of buckets alternately fixed on one andthen the other of said elements, steam-chests exterior to the outer ofsaid rin s, steam-tubes to them from said axle and ports for jets ontosaid outer ring of fixed buckets.

4-. The combination with a rotary steampipe and disk, on said pipe,provided with branches from said pipe and steam-chests on rings ofbuckets on said disks radially Within said jets, of a fixed diskprovidedwith rings of buckets telescoped with the buckets of said rotary diskand provided with an exhaustort.

5. he combination with concentric rings of alternately-fixed and movingrings of buckets, of a steam-pipe, axial to said rings branchestherefrom and moving steamchests on said branches and ports to saidchest.

6. The combination with concentric rings of alternately fixed and movingrings of buckets, a steam-supply pipe axial to said rin s, branch pipesand steam-chest radial to sai axial-pipe ports to said chests exteriorto said rings of buckets, of a wall to the inner edges of the innercircle of buckets.

7. The combination with concentric rings of' alternately static anddynamic rings of buckets, of an axial steam-pipe extending, as

an inte al element, on each side of said rin s of uckets, and branchesfrom said pipe with ported steam-chests.

8. The combination with a rotary steampipe and disk on said pipe rovidedwith ported steam-chests connecte to said pipe, of a static disk rovidedwith rings of buckets concentric witli dynamic rings of buckets,steam-chests and ports, and exhaust-port, the fo'rmerat the greater andthe latter at the least radial distance.
